where can i find a schematic for Stevens mod. 311A
You might find one at a gun shop, gun show or at e-gunparts.com
I have seen them at gun shows. More expensive than a 12 or 20 guage. They are rather rare.
gunpartscorp.com has them listed for $1.70
Yes, Sears, Roebuck and Co. sold the Stevens Model 311A shotgun, which was available in various configurations, including 12 gauge with 2¾ inch chambers and 32-inch barrels in modified and full choke options. The Model 311A was a popular double-barrel shotgun, often marketed through Sears catalogues. If you're looking for specific details, such as production years or pricing, that information can typically be found in vintage Sears catalogs or firearms references.

Joe - That version of the Stevens name was used from 1886 to 1916.
I don't find the Westernfield 530A but be careful: there is a Stevens 530 (1912 to 1918) that is a pump shotgun as well as the Stevens mod 530 (1935 to 1952) double barrel.
Up to $300 in excellent condition.
Numrich Arms (GUNPARTSCORP.COM) lists several parts for the Stevens mod 94 in different gauges, depending on the exact model.
On the one I own the right is mod. the left is full. My 16 ga that I bought when I was 11, I'm 53 now is full and modified. It's killed countless rabbits squirrels, pheasants, quail, ducks and other assorted animals including a deer. Great first gun, but I still love it.
I can't find any reference to a Stevens mod 320 however if it is similar to their mod 124 (12 ga, bolt action, 3 shot box magazine, 1950's manufacture) then you will not find an extended magazine for this gun. Stevens never made a 5 shot magazine for this gun and no after market companies would either. A 12 ga pump with extended tube magazine is a better solution.
Once you cross reference mod 42dl (Sears mod 103.19800) you will find your rifle is really the Marlin arms Mod 80. Parts are available from Numrich Arms at http://www.e-gunparts.com . Your parts and a schematic will show up under the Marlin 80. Good Luck Joe
